Aww mummy, 6 years gap is quite long so totally normal to feel the nerves again! A few of us mums went through similar gaps and honestly, the body does "forget" a bit, so you might feel more aches, the pregnancy hormones hit different, and things feel unfamiliar again, which is why the anxiety is real. My advice is to be extra kind to yourself, maybe schedule your check-ups a bit earlier to put your mind at ease, and don't hesitate to ask your doctor lots of questions (they won't judge, I promise). Also reconnect with your pregnancy buddies or find online groups again, there's something so reassuring about venting to mums who get it, especially when it's been so long. You've done this before, so your body knows what to do, even if your mind needs reminding!
